28-Pin Male Wire Harness Connector with TPA – Technical Overview A 28-pin male wire harness connector with TPA (Terminal Position Assurance) is a robust and reliable interconnect solution designed for secure electrical connections in demanding applications. This connector system ensures high-performance signal and power transmission while offering enhanced mechanical stability and vibration resistance. Key Features 1. 28-Pin Configuration - The connector features 28 male pins arranged in a standardized layout, supporting multiple signal and power circuits. - Suitable for applications requiring moderate to high pin density, such as automotive, industrial controls, and consumer electronics. 2. Terminal Position Assurance (TPA) - The TPA mechanism locks terminals in place, preventing accidental disengagement due to vibration or mechanical stress. - Ensures long-term reliability by maintaining proper terminal alignment and contact integrity. 3. Durable Housing - Constructed from high-temperature-resistant thermoplastics (e.g., PA66, PBT) for durability in harsh environments. - Features a polarized design to prevent incorrect mating and reduce assembly errors. 4. Secure Locking Mechanism - Equipped with a primary locking latch for connector mating stability. - Secondary locks (TPA) provide additional retention for terminals, enhancing overall system reliability. 5. Wide Operating Temperature Range - Typically rated for -40°C to +125°C, making it suitable for automotive and industrial applications. 6. High-Current and Signal Capability - Supports both power (up to several amps per pin) and low-voltage signal transmission. - Gold or tin-plated contacts ensure low resistance and corrosion resistance. 7. Sealed and Unsealed Variants - Available in IP67-rated sealed versions for moisture and dust resistance or standard unsealed versions for indoor use. Applications - Automotive: Engine control units (ECUs), sensors, lighting systems. - Industrial Machinery: PLCs, motor controls, robotics. - Consumer Electronics: Appliances, power supplies, data communication devices. Advantages - Enhanced Reliability: TPA prevents terminal backout, reducing failure risks. - Easy Assembly: Tool-less or low-force insertion for efficient production. - Customization: Compatible with various wire gauges (AWG) and crimp terminals. This 28-pin male connector with TPA is an optimal choice for engineers prioritizing durability, safety, and performance in electrical interconnect systems.
